It also includes a discharge guide groove 4, a waste collection box 5, a material guide bracket 6 and a material shaking drive device 7. The waste collection box 5 is arranged at the front side of the punch press. The cross section of the discharge guide groove 4 is a U-shaped structure with an upper opening. The discharge guide groove is inserted into the adjacent In the gap between the lower pads 2, and the rear end height of the discharge guide groove is higher than the front end height, the waste discharged through the lower end of the blanking hole of the stamping die 1 can fall into the discharge guide groove 4, and the front end of the discharge guide groove 4 is located directly above the waste collection box 5.

One end of the guide bracket 6 is fixedly connected to the moving end of the material shaking drive device 7, and the other end of the guide bracket 6 is fixedly connected to the discharge guide groove 4.

[0025] The material shaking drive device 7 drives the discharge guide groove 4 to shake horizontally back and forth frequently in the front and rear directions through the material guide bracket 6, so that the waste therein is continuously sent forward and finally falls into the waste collection box 5 for collection, avoiding the waste from accumulating between the adjacent lower pads 2 on the workbench 3. There is no need to manually scrape the waste, saving labor, and avoiding excessive waste accumulation, which makes it impossible to discharge the waste smoothly during subsequent blanking processing, resulting in damage to the mold.

[0026] The material shaking driving device 7 is a cylinder, the piston rod of the cylinder can move back and forth horizontally along the extending direction of the discharge guide groove 4, and one end of the material guide bracket 6 is fixedly connected to the piston rod of the cylinder.

[0027] The discharge guide groove 4 is reciprocated back and forth by the cylinder's piston sliding back and forth. In addition, the material shaking drive device 7 can also be a gear rack mechanism or a screw nut mechanism driven by a motor, and the discharge guide groove 4 is reciprocated back and forth by the forward and reverse rotation of the motor. This is an equivalent replacement structure that can be easily thought of by technical personnel in this field based on this application, and it falls within the scope of protection of this application.

[0028] The stamping die 1 is a continuous die. Two or more blanking holes are provided on the stamping die 1 at intervals along the left-right direction. Each blanking hole is directly opposite to the gap between two adjacent lower pads 2. Two or more discharge guide grooves 4 are respectively inserted into the gap between each adjacent lower pad 2 and directly connect to each blanking hole. A transmission shaft 8 extending along the left-right direction is also provided. One end of two or more material guide brackets 6 is fixedly connected to the transmission shaft 8. The other end of each material guide bracket 6 is fixedly connected to the discharge guide groove 4 in a one-to-one correspondence. The transmission shaft 8 is fixedly connected to the moving end of the material shaking drive device 7. By connecting multiple material guide brackets 6 through one transmission shaft 8, there is no need to equip each material guide bracket 6 with a material shaking drive device 7. Only one or two material shaking drive devices 7 are needed to drive all the discharge guide grooves 4 to shake the material synchronously, saving energy.

[0029] The two material shaking driving devices 7 are arranged at intervals along the continuous die feeding direction, and both ends of the transmission shaft 8 are fixedly connected to the moving ends of the two material shaking driving devices 7 respectively.

[0030] The lower end of the material guide bracket 6 is provided with a superior arc-shaped elastic connecting buckle 9, and the superior arc-shaped elastic connecting buckle 9 can be tightly clamped on the circumferential outer side of the transmission shaft 8.

A horizontally extending guide hole is provided on the side wall of the template of the stamping die 1, and the guide rod 11 can be horizontally slidably inserted into the guide hole.

[0033] The limiting baffle 10 blocks the rear end opening of the discharge guide groove 4 to prevent waste from falling from the rear end of the discharge guide groove 4. At the same time, the guide rod 11 on the limiting baffle 10 is plugged into the guide hole on the template side wall of the stamping die 1 to achieve support and limitation of the rear end of the discharge guide groove 4, and at the same time guide the rear end of the discharge guide groove 4 to slide back and forth.

[0037] The rear ends of the two side walls of the U-shaped structure of the discharge guide groove 4 are formed with horizontal contact surfaces 14 by means of fleshing. The horizontal contact surfaces 14 can slide relatively flat against the lower end plane of the stamping die 1. The horizontal contact surfaces 14 slide back and forth along the lower end plane of the die. On the one hand, the rear ends of the U-shaped side walls of the discharge guide groove 4 contact the lower end surface of the stamping die 1 to close the left and right sides of the U-shaped structure, preventing waste from flying out from the left and right sides. On the other hand, it guides the forward and backward movement of the discharge guide groove 4.

[0038] The waste collection box 5 is a funnel-shaped structure with a larger upper opening than a lower opening. A waste collection bag is detachably mounted on the lower opening of the waste collection box 5. Waste can fall into the waste collection bag along the inclined sidewalls of the waste collection box 5 for collection. After entering the waste collection box 5, the waste is directly bagged and collected by utilizing the inclined surface of the waste collection bag, eliminating the need for manual bagging and saving labor.
